Symphoricarpos plant named ‘Kolmaswet’

ABSTRACT

A new and distinct cultivar of  Symphoricarpos  plant named ‘Kolmaswet’, characterized by its compact, upright and outwardly spreading plant habit; short stems and internodes, bushy and dense habit; freely flowering habit; numerous red purple-colored berries; and good garden performance.

Botanical designation: Symphoricarpos alba.

Cultivar denomination: ‘Kolmaswet’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofSymphoricarpos plant, botanically known as Symphoricarpos alba andhereinafter referred to by the name ‘Kolmaswet’.

The new Symphoricarpos plant is a product of a planned breeding programconducted by the Inventor in Heelsum, The Netherlands. The objective ofthe breeding program is to create new pot-type Symphoricarpos cultivarswith strong foliage and numerous attractive fruits.

The new Symphoricarpos plant originated from a cross-pollination in 2001in Heelsum, The Netherlands of a proprietary selection of Symphoricarposalba identified as code number 99-23, not patented, as the female, orseed parent with a proprietary selection of Symphoricarpos albaidentified as code number 00-17, not patented, as the male, or pollen,parent. The new Symphoricarpos was discovered and selected by theInventor as a single flowering plant within the progeny of the statedcross-pollination in a controlled greenhouse environment in Heelsum, TheNetherlands in 2003.

Asexual reproduction of the new Symphoricarpos plant by vegetativecuttings in Boskoop, The Netherlands since 2003 has shown that theunique features of this new Symphoricarpos plant are stable andreproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Symphoricarpos have not been observed under allpossible environmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature and light intensitywithout, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Kolmaswet’. These characteristics incombination distinguish ‘Kolmaswet’ as a new and distinct cultivar ofSymphoricarpos:

-   -   1. Compact, upright and outwardly spreading plant habit.    -   2. Short stems and internodes, bushy and dense habit.    -   3. Freely flowering habit.    -   4. Numerous red purple-colored berries.    -   5. Good garden performance.

Plants of the new Symphoricarpos differ primarily from plants of thefemale parent selection in the following characteristics:

-   -   1. Plants of the new Symphoricarpos have shorter lateral        branches than plants of the female parent selection.    -   2. Plants of the new Symphoricarpos and the female parent        selection differ in fruit color as plants of the female parent        selection have white-colored berries.

Plants of the new Symphoricarpos differ primarily from plants of themale parent selection in the following characteristics:

-   -   1. Plants of the new Symphoricarpos have shorter lateral        branches than plants of the male parent selection.    -   2. Plants of the new Symphoricarpos have stronger lateral        branches than plants of the male parent selection.

Plants of the new Symphoricarpos can be compared to plants ofSymphoricarpos ‘Scarlet Pearl’, disclosed in U.S. Plant Pat. No. 13,244.Plants of the new Symphoricarpos differ primarily from plants of‘Scarlet Pearl’ in plant habit as plants of the new Symphoricarpos aremore compact and denser than plants of ‘Scarlet Pearl’.
